Version Control System for LCGT

This page contains information for using version control system, subversion, for various LCGT tasks.

Introduction, why version control system ?

Version control system (VCS) is a computer tool to manage the history of various files you work on. Usually, files are documents or program codes, but you can use it for managing virtually any type of files. It keeps track of the changes you make to the files and let you roll back to any previous version if you want. The VCS is particularly useful when several people are working on a single set of files, for example, a group of people writing a paper, or several people developing a simulation code together. Subversion (svn) is a popular VCS and used by many projects around the world. There is an svn repository for LCGT. LCGT collaborators are strongly encouraged to use this svn repository for any applicable tasks.

For more detailed reasonings for the use of VCS, see here.
